Explanation:

Answer:

The age difference between the oldest and the youngest is 48.

Explanation:

Given the following data;

The ratio of the ages of Kisii (K) and Esinam (E) is 3:5.

The ratio of the ages of Esinam (E) and Larry (L) is 3:5.

The sum of the ages of all three is 147.

Since the age of Esinam is common in both ratios, we find the lowest common multiple (LCM);

LCM of 3,5 = 15.

Hence, the ratio of the three ages is now;

K:E:L = 9:15:25

Let their ages be denoted by x;

[tex]K:E:L = 9x:15x:25x[/tex]

The sum of all three ages is;

9x + 15x + 25x = 147

49x = 147

x = 147/49

x = 3.

To find the age difference between the oldest and the youngest;

The oldest is Esinam = 25x

The youngest is Kisii = 9x

Therefore, 25x - 9x = 16x

Substituting the value of x, we have;

x = 3; 16x = 16(3) = 48.

The age difference between the oldest and the youngest is 48.

Explanation

It should be understood that respiration is the process whereby organisms exchange gases with their environments.

And the two types are aerobic and anaerobic respiration.

Aerobic respiration is the type of respiration that occurs in the presence of oxygen, while the anaerobic respiration is the type of respiration that occurs in the absence of oxygen.

The examples of organisms that are used in making alcohol and yoghurt are Sacharomyces cerevisae, which is yeast, and Lactobacilli spp respectively.

Answer:

toxic buildup.

Explanation:

The excretory system has to do with excreting perilous, harmful materials from the body. If it malfunctions, these materials stay in the body. Therefore, the result of a malfunctioning excretory system would be toxic buildup.

Answer:

=> There will be mutation of gene in each strain.

=> The offsprings are wild type.

Explanation:

So, we are given the following main or Important information or data which I going to assist us in solving this particular Question or problem:

=> There is an isolated a true-breeding strain of wingless Drosophila.

=> " six other true-breeding strains of Drosophila with the same mutant phenotype have been isolated independently in the lab."

Therefore, the flies that belong to different complementation groups will cause MUTATION TO OCCUR ON THE SAME GENE.

Mutation will occur because here we have dual but different genomes and when you take a look at these genomes they both have a trait of recessiveness and this combination of the genomes will cause the mutation.

Quick note: on the strain, occurence if different mutation might or might not occur.

Explanation:

Butter, as good as it is, is not exactly good for us. Butter is an animal fat, or a saturated fat. This means that at room temperature these fats will remain solid. There is some science behind it and ill say this quickly, it has to do with the carbon atoms being packed with hydrogen atoms. This allows them to intertwine and be solid. The Vegetable Oil being unsaturated, a plant fat, is good for us! These are missing some of the atoms needed to make them stand up straight and be solid. So these are always liquid at room temperature! :)

We have that for the Question "Both vegetable oil and butter are made up of fats.  Why is butter a solid at room temperature, while vegetable oil is a liquid?"

Answer:

Explanation:

Butter contains more saturated fat., vegetable oil contains more unsaturated fat.

Melting point of Saturated fat less than melting point of Unsaturated fat

Intermolecular interactions in saturated fats greater than Intermolecular interactions in Unsaturated fats

Saturated molecules are so close and forms a solid.  UnSaturated molecules are not so close and forms a liquid at room temperature

A gene is a short section of DNA. your genes contain instructions that tell your cells to make molecules called protein

Answer:

Basically gene produces a functional product such as a protein which regulates the functioning of our cells via carrying out different processess.

Explanation:

Genes are short segments of our DNA that code for functional products such as proteins. Proteins basically do everything in your cells and your phenotype (what you look like and how you cells behave) everything is controlled by these functional products that a gene makes.

Higher the body temperature, it would disrupt the shape of the active site of the enzyme , which will reduce its activity, or prevent it from working. The enzyme will have been denatured also the protein which can also lead to death.

Answer:

When a person has high fever, it's body temperature increases.

When the temperature is too high, enzyme molecules vibrate vigorously causing it to lost it's shapes and active sites.

Then, started to denatured and eventually, the enzyme died and no longer able to function.

Answer:

During secondary succession, the soil isn't damaged hence there is no need for pioneering species such as lichens to dissolve the damaged soil into organic ones that can sustain more complex plants.

Explanation:

Secondary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals recolonize a habitatafter a major disturbance—such as a devastating flood, wildfire, landslide, lavaflow, or human activity (e.g., farming or road or building construction)—significantly alters an area but has not rendered it completely lifeless. Secondary succession is distinguished from primary succession, in which a biological community develops where no life had existed

Secondary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals recolonize a habitatafter a major disturbance—such as a devastating flood, wildfire, landslide, lavaflow, or human activity (e.g., farming or road or building construction)—significantly alters an area but has not rendered it completely lifeless. Secondary succession is distinguished from primary succession, in which a biological community develops where no life had existed previously.

Secondary succession follows a major disturbance, such as a fire or a flood. The stages of secondary succession are similar to those of primary succession; however, primary succession always begins on a barren surface, whereas secondary succession begins in environments that already possess soil. In addition, through a process called old-field succession, farmland that has been abandoned may undergo secondary succession.

Secondary succession takes place where a disturbance did not eliminate all life and nutrients from the environment. Although fire, flooding, and other disturbances may bring visible ruin to a landscape, drive out many plants and animals, and set back the biological community to an earlier stage, the habitat is not lifeless, because the soil retains nutrients and seeds that were set down before the disturbance occurred. Buried seeds can sprout shortly after the effects of the disturbance pass, and some may have greater success from reduced competition and reduced shading. Some species may be adapted to the frequent passage of a particular disturbance. For example, the jack pine (Pinus banksiana), a tree species common in the northeastern U.S. and Canada, requires heat from a wildfire to open its cones (strobili) before seeds can be spread for new growth.

Answer:

E

Explanation:

Some are heterotrophic and the other are autotrophic.

Some of the energy in the system has moved from one organism to another during the 3 months. Hence option E is correct.

Aquarium is defined as any size tank with at least one transparent side used to house and display aquatic plants and animals. Like zoos, aquariums offer enjoyable leisure and amusement activities that also serve as locations for scientific research, education, animal care, and conservation.

Your fish may die if there are any significant temperature variations in their tank. Do not place your tank close to cooling vents or in a location that gets a lot of sunlight. A steady water temperature of 72°F to 82°F is required for freshwater fish, while 75°F to 80°F is ideal for saltwater fish.

Thus, some of the energy in the system has moved from one organism to another during the 3 months. Hence option E is correct.

Yes, this statement is TRUE cells will generally divide when they're too large

The larger a cell becomes, the more demands the cell places on its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane.

The mitotic phase follows interphase. Mitosis is nuclear division during which duplicated chromosomes are segregated and distributed into daughter nuclei. Usually the cell will divide after mitosis in a process called cytokinesis in which the cytoplasm is divided and two daughter cells are formed.

Glycosidic Bonds

Explanation:

Glycosidic Bonds are a type of covelant bond that form between two or more 5 carbon sugar macro-molecules(like glucose). Hydrogen bonds are an attraction between hydrogen atoms, not a real sharing or trading of electrons, as seen with ionic and covelant bonds, while they are essestial to life in water, they generally do not have a strong effect in the building of macromolecules. Therefore, that is incorrect. Phosphodiester, ester, and peptide bonds all occur between different macro-molecules, none of which include glucose(5 carbon sugar). Therefore, the answer is #4.

Explanation:

In this lecture you learned that due to evolutionary descent, organisms share many of the same genes and proteins. However, distantly related organisms have more DNA differences than closely related organisms.

Organic evolution general refers to the descents, with modification, of organisms from common ancestors. Hence, organisms that share the same ancestors share several similar genes and proteins due to their common lineage. The closer the organisms, the more similar their genes and proteins, and the distant the organisms, the more dissimilar their genes.
